I’m reading excerpts from the Upanishads in the Hinduism chapter of Novak’s The World’s Wisdom and keep thinking to make notes of parallels to A Course in Miracles.
…Who sees all beings in his own Self, and his own Self in all beings, loses all fear. (Isa Upanishad, p. 9)
… When a sage sees this great Unity and his Self has become all beings, what delusion and what sorry can ever be near him? (Isa Upanishad, p 10)
If the slayer thinks that he kills, and if the slain thinks that he dies, niether knows the ways of truth. The Eternal in man cannot kill: the Eternal in man cannot die. (Katha Upanishad, p. 13)
When consciousness of the Atman manifests itself, man becomes free from the jaws of death. (Katha Upanishad, p. 13)
Who sees the many and not the ONE, wanders on from death to death…. Even by the mind this truth is to be learned: there are not many but only ONE. Who sees variety and not the unity wanders on from death to death…. As water raining on a mountain-ridge runds down the rocks on all sides, so the man who sees variety of things runs after them on all sides. But as pure water raining on pure water becomes one and the same, so becomes, O Nachiketas, the soul of the sage who knows. (Katha Upanishad, p. 13)
Only the wise who see [the Spirit] in their souls attain the joy eternal. (Katha Upanishad, p. 14)
Obviously the parallels are (mainly?) the stuff about perceiving the oneness of God-ourselves-others and that perception leading to peace and joy. It seems, though, that ACIM teaches a more active love of others (at least, active in the sense that it helps daily relationships) while the Upanishads seems to teach more of a pulling away from others??
